Yukon Denali factory head unit clock issue

[MikeSelf]

I have an 07 Yukon Denali with the stock head unit. It is the touchscreen NAV Bose system. For a while now, the clock insists on being an hour behind. I can fix it by setting the clock back to the correct hour, but the next time I start up, it changes back. It never looses more than one hour and only happens after I set the time to the correct hour. Anyone else ever had this issue? Is there a quick fix? I've toyed around in the various menus to no avail.

Yes. There is a setting for daylight savings. Turn that off or on and it will be corrected.

Thanks, I thought that might be the issue but couldn't manage to find the setting. I'll go searching some more now that I know it should be there.
